Sure! That's one of the more complicated things, perhaps needlessly so haha, but I like how it turned out so fuckit!
So there are mainly 3 tracks that all go to an overall bus. Each track is filtered so it sits in a certain frequency area, there's a sub track, a midrange meat track, and then a distorted grit track. The sub track is actually made from the MIDI when I originally programmed the bass for the demo, I used the JST sub destroyer synth for the tone of that one. The main meat track is using a bass amp sim, in this case it was UAD Nigel. The grit track is using some pedals, a Dark Glass bass distortion into a Sansamp Bass DI.
Then these all get bussed together and processed to hell and back. Nothing too crazy just lots of EQ, compression, and some saturation, stuff like that. On this I believe I used the Equilibrium EQ, the UBK compressor from Kush, and some Slate Digital stuff like VCC. There's also a tiny bit of filtered stereo chorus from UAD to give it a bit more width. Other 'tricks' that add to the fun include an additional sub synth in parts like chorus and breakdowns, and additional distorted and / or slap tracks in certain heavy parts like breakdowns to really make them extra crush.
